Ethyl 4-(5-bromo-2-hy­droxy­phen­yl)-2,7,7-trimethyl-5-oxo-1,4,5,6,7,8-hexa­hydro­quinoline-3-carboxyl­ate

In the title compound, C(21)H(24)BrNO(4), the dihedral angle between the heterocyclic ring and the pendant aromatic ring is 80.20 (13)°. The hexahydroquinone [i.e. the one with the C=O group] ring adopts a sofa conformation. An intra­molecular O—H⋯O hydrogen bond generates an S(6) ring motif. The ethyl group is disordered over two sets of sites with a refined site occupancy ratio of 0.633 (10):0.366 (10). In the crystal, mol­ecules are linked by N—H⋯O inter­actions, forming chains parallel to [101]. There are no significant C—H⋯π or π–π inter­actions in the crystal structure.
